I turned the mill and lathe in my friends garage and i am getting overvolt alarms. These machines have been wired for years and never had this problem. When i check the voltage there are 2 wires coming in that are 110 each leg and on the underside there are 3 wires that come out and the middle wire has no voltage coming out. Im assuming it takes 220 in and distributes it into 3 lines but the fact that both machines have the same alarm has me baffled. Can anyone shed light on this please? Thanks guys
The mill is haas tm1
Lathe is tl1
